Microarrays are versatile tools for high throughput screening. Nevertheless they are severely limited. Therefore the idea arose why not to copy microarrays? Why not make DNA, RNA and protein microarrays as high quality copies of a high quality original? It worked fine for text books and images. So why not apply it for DNA? Why not build a biomolecule copying machine? A biomolecule xeroxer?

DNA origami is a powerful method for the programmable assembly of nanoscale molecular structures. For applications of these structures as functional biomaterials, the study of reaction kinetics and dynamic processes in real time and with high spatial resolution becomes increasingly important.

The application shows that the mode and dynamics of trypanosome locomotion are a trait of life within a crowded environment. Using high-speed fluorescence microscopy and ordered micro-pillar arrays we show that the parasites mode of motility is adapted to the density of cells in blood.

Light sheet fluorescence microscopy has previously been demonstrated on a commercially available inverted fluorescence microscope frame using the method of oblique plane microscopy (OPM). In this paper, OPM is adapted to allow time-lapse 3-D imaging of 3-D biological cultures in commercially available glass-bottomed 96-well plates using a stage-scanning OPM approach (ssOPM).

Multiple optical measurement techniques have been applied for the investigation of a propeller-wing wind tunnel model. The (half) wind tunnel model is equipped with a nine bladed propeller and its wing has active Coanda blowing over the whole span of the wing.

Particle Image Velocimetry not only allows visualizing the airflow around the bike and rider, but also accurately measures the flow in detail. Development engineers use these results to optimize the performance of bike and clothing and help André Greipel in this way to reach new sportive achievements.

COMTESSA stands for Camera Observation and Modelling of 4D Tracer Dispersion in the Atmosphere. COMTESSA’s vision is to elevate the theory and simulation of turbulent tracer dispersion in the atmosphere to a new level by performing completely novel high-resolution 4D measurements.

Large-volume volumetric flow experiments and their results: The first of these, investigating a thermal plume at low velocities (up to 0.35 m/s) demonstrates the abilities and requirements to reach volume sizes up to and probably beyond one cubic meter.

A novel approach to the evaluation of time resolved particle-based tomographic data is introduced. By seizing the time information contained in such datasets, a very fast and accurate tracking of nearly all particles within the measurement domain is achieved at seeding densities comparable to (and probably above) the thresholds for tomographic PIV.

The physical mechanism underlying this optically induced phase transition process is discussed. It is demonstrated that this phase change can, in principle, be used for an all-optical “write–read–erase” memory device.

Crystal nucleation is important to control the product properties in industrial crystallization processes. In this work, we propose a simple method to manufacture such devices from polycarbonate as an alternative to conventional chips made of poly (dimethylsiloxane).

General knowledge tells us that oil and water do not mix. However, if we understand the mixing of oil and water, we better understand the behavior of spilled coffee, we can predict how long it will take for paint to dry, four our glass of beer to lose its 'fizz' and we can understand why the olive oil and vinegar in out 'vinaigrette' indeed refuses to mix.

This work describes details to the principle, design and construction of the proton microscope as well as first measurements and simulations of essential components like magnetic lenses, a collimator and a scintillator screen.

Blue Paw Artists has been making documentary films for international broadcasters like National Geographic, Discovery and the BBC and domestic clients including ZDF, ARTE, ARD and BR for the last 20 years.

The high-speed impact of a droplet on a bulk fluid at high Weber number is not well understood but is relevant to the production of marine aerosol by raindrop impact on the sea surface. These splashes produce a subsurface cavity and a crown which closes into a bubble canopy, but a floating layer of immiscible oil, such as a crude oil slick, alters the splash dynamics.

Filming the welding process is accompanied by an additional obstacle in addition to the high-speeds: During this process, a bright light covers the actual joint area. The bright process glare can be suppressed by a trick. As the glare is usually whitely, it can be concluded that its intensity is spread almost constantly across all (visible) wavelengths.

The temporal behavior of mode instabilities in active large mode area fibers is experimentally investigated in detail. Thus, apart from the onset threshold of mode instabilities, the output beam is characterized using both high-speed camera measurements with 20,000 frames per second and photodiode traces.

The vibration created by a sonic toothbrush ranges between 200 and 400 Hz. This means 24,000 - 48,000 movements per minute. With high-speed vibration, the sonic vibrating toothbrush can effectively clean the teeth and keep the mouth healthy. But have you ever seen how it works? What happens when it runs at high speed?

Ultrasonic welding has its unique advantages over traditional welding techniques. When the solder is heated and then melted, the ultrasonic helps to remove the air between the melted solder and the surface and to form a robust structure.

High-speed imaging of a droplet shows that the droplet behaves like a ball when it falls onto a piece of waterproof material. It will be compressed and bounces into the air after it drops and hits the material. To film this amazing phenomenon, a high-speed camera that can achieve extremely low exposure time, high frame rate and most importantly high sensitivity to capture the moment is required to show you the truth.

Additive manufacturing is currently making a giant leap towards mass production. Technological processes have matured and industrial 3D printing has proven to be an efficient manufacturing process. EOS is launching an innovative quality monitoring solution for optical tomography. The heart of the system is the pco.edge sCMOS camera.

Silicon carbide (SiC) is a wide bandgap semiconductor, which is especially used for high-power, high-temperature and high-frequency devices due to its high energy efficiency. Despite great improvements in the material quality of SiC substrates and epitaxial wafers within the last years, critical defects like stacking faults (SFs) and basal plane dislocations (BPDs) can still lead to bipolar degradation and finally to complete failure of the device.
